I am trying to figure out how to fix some issues I have been having with heroic games launcher, every-time I have to use the files chooser for example setting a wine prefix or selecting an executable the entire app freezes. I am not totally sure how to fix this.
If it’s the flatpak version, try the package manager one. The one on flathub didn’t integrate very well and only really worked for steam games.
Sadly I’m on steamOS
